For the third consecutive year, UCMP participated in the Bay Area Science Festival at AT&T Park as one of several Science@Cal exhibitors. The November 2, 2013, festival drew more than 28,000 science fans and Lisa White, Tripti Bhattacharya, and volunteer CJ Dunford staffed a UCMP table. With a theme of "Who lived here before the Giants?," the UCMP fossil display and activities were a big hit with the little fans!
Examples of the scientific illustrator's art
Early this past year, as UCMP continued its efforts to catalog the museum's archival collections, a small collection of original scientific illustrations were rediscovered. These pieces represent the work of a number of talented scientific illustrators who produced images for the publications of UCMP curators, staff, and students between the years 1934 and 1991. All who saw these works were impressed by the skill, patience, and steady hand required to produce them. Therefore, it was decided that this art should be the focus of the 2014 calendar. Thumbnails of each month's primary illustrations can be seen below.
Contact Chris Mejia at email@example.com or call 510-642-1821 to obtain your 2014 UCMP Fossil Treasures Calendar, a tribute to the museum's scientific illustrators. They're only $10 each (plus postage) and all proceeds support museum research, education, and outreach.
And for the collectors out there, a few copies of the 2013 UCMP Fossil Treasures Calendar are still available for a mere $2.
In the summer of 1902, US Geological Survey and UC Berkeley paleontology crews had a chance meeting in the field near Redding. Along with Merriam, the Berkeley crew included preparator Eustace Furlong, as well as museum benefactress Annie Alexander and her traveling companion, Katherine Jones. Jones' diary recorded Alexander's encounter with Joseph Diller of the US Geological Survey while washing her hair in a stream. Diller asked "all sorts of leading questions as to the plans of our party and in fact knew our movements as well as we did." Alexander "gave as evasive answers as possible"1, not wanting Diller to co-opt their discoveries. Diller spent his career in the Pacific Northwest, and although not a paleontologist, he collected hundreds of fossils for the US Geological Survey. Despite the suspicion surrounding their initial meeting, Diller later referred Merriam to exposures of the Hosselkus Limestone in Cow Creek, where in 1910, Merriam and his crew discovered the skull and partial skeleton of the ichthyosaur, Shastasaurus.
Working closely with the USGS and associated UCMP collections, it is clear that UCMP and US Geological Survey staff visited many of the same places. I enjoyed reading this confirmation of such encounters. It seems fitting that the fossils collected by these two storied institutions are now reunited in the UC Museum of Paleontology.

Werning did histologic studies of the six-foot-long specimen and found that the animal was not even one-year old when it died. Sarah reported that "Dinosaurs have yearly growth rings in their bone tissue, like trees. But we didn't see even one ring. That means it grew to a quarter of adult size [25 feet] in less than a year."
Three-dimensional scans of the entire skeleton were made and are freely accessible online. See the paper, along with the 3D scans, in the open-access journal PeerJ. Co-authors on the paper are Andrew Farke of the Raymond M. Alf Museum of Paleontology, Claremont, California, and Webb students Derek Chok, Annisa Herrero, and Brandon Scolieri.

On September 23-25, 2013, the UCMP hosted a workshop on Integrating Molecular Phylogenies and the Fossil Record supported by the France-Berkeley Fund. Led by UCMP Director Charles Marshall and Hélène Morlon from École Polytechnique in France, the workshop brought together leading researchers who are developing methods for inferring diversity dynamics using molecular phylogenies or fossil data. The gathering of approximately 25 people included UC Berkeley faculty and UCMP graduate students and provided an opportunity to integrate both sources of information in a common framework.
Why New Mexico? Like someone else put it "it ain't new and it sure ain't Mexico!" So why make the trek? To attend the Carboniferous-Permian Transition Meeting! Five members of the Looy Lab piled into a van and drove all the way from Berkeley to Albuquerque. With the enormous number of meetings and conferences being organized, why did we decide to go to this particular one?
I think there is a checklist that most people go over before they decide on which conference to attend. In random order:
- Is the topic of the conference relevant (or at least a session of it)?
- Can I afford the conference fees?
- Will this gathering allow me to collaborate with some of the other attendees?
- Are there going to be other people attending that I desperately would like to talk to (but then end up being too shy to actually do so)?
- Is it in a cool location and does it offer any interesting field trips?
- Will I have something new to present by the time the conference rolls around (or do I dust off some older material)
- Is this the real conference I'm signing up for, or a bogus one where some fraud takes my money and disappears into the sunset? I am not kidding, this actually happens!
- Will I have time to prepare for the meeting and will I have time to actually attend it?
- How much does it cost to get there? Can I find a grant that covers the costs of travel?
These are all things to consider. If the answers to the questions above are 'yes,' or at least positive, then the conference might be worth going to. And that is how we ended up in Albuquerque. Because the conference included two field trips on which we were hoping to collect a lot of fossils, and there were five of us going to the same conference, it made sense to drive. A nice bonus was that we got to see some cool field sites along the way.
After two days of driving we arrived in Albuquerque. The conference was held at the New Mexico Museum of Natural History and Science. The conference room itself was as boring as any other conference room, but during the breaks and the banquet we got to wander around in the museum, which was really nice. It is definitely worth a visit if you're ever in Albuquerque.
The first day of the conference was mostly about stratigraphic issues. Where is the Carboniferous-Permian boundary exactly? Do we base this on findings in Russia, China or perhaps the U.S.? There was definitely quite a bit of disagreement on that particular topic. More applied research was discussed the second day and on the third day, Wednesday, it was our turn. Cindy Looy talked about branch abscission, Robert Stevenson showed us cool movie clips of auto-rotating winged seeds, Jeff Benca discussed patterns of leaf margins and what that does and does not tell us, and I talked about phytoliths. We all got great responses. Sometimes audiences can look like they're about to go into hibernation, but not this time. They were engaged and had good questions and recommendations for all four of us.
We also got to go on two fieldtrips. The first one was to the Kinney Brick Quarry where sediments from the Pennsylvanian, the "younger" half of the Carboniferous, crop out. The locality is considered to be a Lagerstätte, an extremely fossiliferous site with excellent preservation. On another trip, they took us east of Socorro, where the Upper Carboniferous and Lower Permian deposits are exposed along the eastern margin of the Rio Grande rift. This gave us the opportunity to collect a lot of plant fossils. We collected more than six big boxes of material. It will take a while to work our way through all of it, but that won't stop us from collecting more fossils in the meantime. Once paleobotanists are on a roll, nothing will stop them. Not even The Thing, unfortunately.
The upper Miocene-Pliocene Purisima Formation near Capitola, California, is well known among avid fossil collectors and popular with beachcombers. While this seaside shallow marine deposit contains rich assemblages of clams, snails and other invertebrates, fossil vertebrates such as whales, fishes, and birds are the most prized. Happily this is a case in which amateurs and scientists have often partnered to exchange fossils and report findings. Fossil hunters Frank Perry, Stan Jarocki, and Bobby Boessenecker recently donated several important fossils from the Purisima Formation to the UCMP: a five-million-year-old whale skull and two ear bones from dolphin-like marine mammals. Descriptions of these fossils were published in the journal Acta Paleontologica Polonica as reported by the San Francisco Chronicle.
Você fala português? If so, you’ll be pleased to learn about Understanding Science’s new Portuguese translation, led by Unversidade de Lisboa Principal Researcher Nuno P. Barradas and his team. Nuno and colleagues recently promoted Understanding Science in Portuguese at a community science event in the town of Estremoz, east of Lisbon. Science on the Streets was organized by Portugal’s national agency for public awareness of science, Ciência Viva ("Living Science"), and the Understanding Science flowchart featured prominently in the display!
How do natural history museums build their collections? The UCMP's fossil collection is largely a product of decades of field work by past and present researchers. As the State's fossil repository, the museum also receives a large number of fossil finds from construction sites in California (for example, the Caldecott Tunnel). Another, perhaps less appreciated means of acquiring scientifically valuable specimens, is specimen exchange between institutions — it's a bit like a holiday gift exchange but without the surprise factor, and the gifts are appreciated by all participants.
If you have visited the Valley Life Sciences Building (VLSB) at Cal recently, you may have seen the skeleton of an ichthyosaur (Stenopterygius, UCMP specimen no. 116080) just down the hall from where the popular T. rex stands. It's a marine reptile that superficially looks like a big fish or dolphin; it lived during the Jurassic Period, about 180 million years ago.
How did this skeleton, which was found in Germany, end up in the UCMP? You guessed it — specimen exchange! The story actually begins in the early 20th Century, before the museum was established. We know this because of an old letter found in the archival collections at The Bancroft Library on campus.
Written in 1912, this letter from German paleontologist Friedrich von Huene to John C. Merriam (who at the time was the Chair of the Department of Paleontology at Berkeley) describes ichthyosaur specimens that were being packed for shipment to California. Item No. 1 in von Huene's list ("big specimen, 3.50 m long: skeleton good, skull bad") is the skeleton on display today. In exchange, von Huene asks for specimens of the dire wolf (Canis dirus) and saber-toothed cat — two iconic carnivores from the Pleistocene "tar pits" of Rancho La Brea in Los Angeles, where their bones had been freshly dug out by Merriam and his crew. This exchange was presumably a win-win deal for the two researchers because Merriam had a strong interest in ichthyosaurs, and von Huene had just toured the United States, visiting museums and possibly collecting fossils at the La Brea tar pits1.
The ichthyosaur made it across the ocean. We don't know what shape the specimen was in when it arrived in the East Bay after what must have been a treacherous journey for heavy fossils. In the late 1970s, a dozen or so pieces of the skeleton were found (reportedly under the Hearst swimming pool) and given to the Senior Museum Preparator, Mark Goodwin, for repair. After exquisite restoration by Mark (who is now an Assistant Director of UCMP), the ichthyosaur was reborn and put on display in the Earth Sciences Building (now McCone Hall), where it remained until 1995.
That year, the museum moved from the Earth Sciences Building to VLSB, and the ichthyosaur went into storage at the Clark Kerr Campus. But in 2009, UCMP Director Roy Caldwell had the specimen retrieved and displayed in its current location, where it now catches the eye of building visitors and residents alike. Like ancient artifacts in art galleries, many specimens in natural history museums have long and complicated post-discovery histories of their own. And, of course, we would know very little of that history without the documents archived at The Bancroft Library and UCMP.
Finally, what happened to the exchange specimens from Berkeley? We have not found a record of shipment from California, but two mounted skeletons of dire wolf and saber-toothed cat in the Palaeontological Collection at the University of Tübingen (where von Huene worked) may be the gifts from Merriam to his colleague. Can you spot the carnivore skeletons in one of their exhibit halls?

Tony Barnosky, UCMP Curator and Professor of Integrative Biology, discussed a consensus statement to world leaders regarding global change, Maintaining Humanity's Life Support Systems in the 21st Century, this past week in an interview by KQED Science Editor Craig Miller.
Barnosky has been working with the California Office of the Governor to promote science-based solutions to global change problems. With 15 other global change scientists he developed the scientific consensus statement, which has now found its way into a number of state, national, and international discussions about environmental solutions. Since the release of the statement in May, more than 1,000 scientists around the world have endorsed it. Join the scientists and add your name as an endorser of the statement.
